l.To all wtomt may-ootcewtj: p

Beutlnown that I,- JosEPrrJ. lPVIA'SKIN,

a citizen o'f the United States, residing at Stockton, countyof Sanloaquin, State of California, ,have invented certain" new Tand usefulz'lmprovements Vin Combination" Locks and I do declare the following to be a full, clear, and'exact description of the same, ref'- erence'being had to the accompanying drawings,A land ,tofthe characters of reference marked' thereon,`which form a part-of this application. f

` This invention vrelates lto improvements I in combination locks, 'and' particularly to a typeada'pted to'be mounted on Athe steering column vof a motor vehicle to lock the. steer# f A ing post againstv movement-whendesired,

thus preventing the theft of the vehicle.

The principal object of mylvinvention` is 'tofprovide-a looking device for the purpose specified, with a simpleyet eiicientrcombination installed in connection therewith,

which, whenv the locking lugis engaged withf the post, must be correctly worked in order to be able toarelease-the lock.` A i Q Another object is to so arrange-'the lock'- ing members that while a positive lock is assurechat the Sametime the' post may be manipulated to acertain extentbefore the lock will take effect,rthus avoiding conflict with the lawsV of certain states,which specify thata vehicle must not be left rigidly locked,

` Thejdevijce may'also beadapted for' use with safes, to lock the slidinglbolts against movement,` the locking member' working lequally well with` a turn-able pstf'or a sliding bolt.

jl'jlhese objects I accomplish by. means of such structure and'relative arrangement o f partsV as will fully appear byV aperusal `of 'the following specification and claims.

In the drawings similar characters of reference indicate corresponding parts in the., several views.

An inwardly projecting flange 19, forming a Vcam-track, is provided on `the vinner periphery of the cap, and is adapted to en- Y gage and ride under a shoulder 20. provided -on the lug 8.

A similar but necessarily shorter track-f1ange 21 is'formed on the central hub 22 of the capk and is adapted to V ride underand Aengage `a shoulder 23 on the pin 14, these tracks slanting from end to end a distance sufficient to move the bolt andpin\ clear of the post 7 andv the track for the latf ter being positioned relative to the track for i 'i the former, to take hold of and move the pin only after the bolt hasbeenmoved'a pre# determined distance. The operation of the lock is as follows: Presume that the lock is engagedv as shown y in Fig. '2. henthe cap is turned in a clockwise directionfaccording to the showing of the vrdrawing vin the present instance) the track 19 rst engages the bolt 8 and raises the same clear of the post'7, without interference with the ldog 18,the "slot 8a in the body for said bolt allowing lsufhcient play of the lug to allow it to pass by the dog. When the bolt 8 is yraised toY a certain extent, the track 21 engages the pin 14, likewise raising the same clear of the'post socket.A At the same time the upper catch oie the dog, the latter moving about its fixed pivotal connection with the member 17 engages the 'upper notch 120i the bolt 8.

As long as the cap is maintained in a position to hold the bolt and pin as described and as shown in Fig. 4 the post may be freely turned.V When the cap'is turned in the opposite direction, thus lowering the tracksfrom under the bolt and pin,` no, movement of' the latter members will occur as long as their inner ends are not in alinement with the post socket and slot. The post is thereforefree' to be turned until such alinement takes. place. l

Since the dog is engaging the bolt, the lat-V ter cannot drop into the slot first, but the pin is free to do so, as shown in Fig. 5.Y

The position of the catches of4 the dog is i thus almost instantaneously reversed that the lower catch thereon'engagesn the lower` 4notch 13 on the bolt 8, thus again preventingv incr/,27s

course force the pin'out kof the post socket (the latter being smooth and rounded as stated.)

The members shown in Fig. 6, the dog being disengaged froml both bolt-notches. Then lwhen the or later) to aline the slotand socket Vwith the bolt and pin, both'thesemembers inde-V "seribed combination :M'Fins 24 are readily positioned and journaled in the flange 2, ythe center lines thereof being in alinement with the floor of the body. O'n the inner ends of the pins are semispherical members 25, seated in `sockets 26 in thebody, the corresponding halves 27 of said spheres vbeing adapted then assume the Apositionas ypost is again turned (as it must be sooner t0 seat in sockets 28 in the flange 1()SL of the the pins on the outside of the body are oddshaped heads 29, each one being set at a dil'erent position with regard to the spheri- V'cal member on the corresponding pin. Each head is provided with a pointer 30, which has a spring-pressed pin 30ad therein adapted to register with any one of a number of radial slits 31, on the body, s0 that the combination vmay be worked in the dark if nec# essary.

lt will be evident therefore that unless the 'cal member is in alinement with'the flush vsurface of. the body and cap, the'latter cannot be rotated, since as soon as any one of the pins is'turned. past this point, one edge of' vthe spherical member Xed thereon will project` into the socket in the cap, while lthe independent spherical member will project into the body socket a corresponding amount. All the spherical members must have their split linesV flush with the body, and as they cannot be seen, their positions are determined by the alinement of the'head pointers with the radial' slits on the body. Since the heads may be mounted on the rpins so' as to have each pointer register with a different slit, to give the same alinement of all the spherical members, a simple yet. effective combination is formed.'

The cap may be centered and held on the body by means yof a screw 32, but it is 'also held on in a more positive manner by means of opposed pins 33 fixed to and projecting inwardly of the flange 2, which pins ride Vsplit line between the co-operatingspheri saidygroove havingopposed vertical grooves 35 communicating with the inner edge of the 'ange l()2L to enable the capj'to beremoved when the pins aline withsaidgrooves 35, the latter being s o positioned that this is impossible when `thelocking lug 8 is iny its flocking positio'm andwhen the'combi'nation sockets are in lalinement i It will thus be seenV that it will be impossible V,to disrupt or remove the device unless the Vparts are actually wrecked, since the cap cannot be removed when the lock is engaged, and the cap 5 is also prevented from being removed as the heads of the screws or 'bolts 6 are inside the body.

A spring catch member C is mounted on the cap l0 and is adapted t0 engage'with the edge of the flange 2 at predetermined points in therelative positioning of the cap and body, so that the operator may know when the lug and pin are raised, when they l are released, and at what point the cap mayV be removed Jfrom the body.

For safe-door purposes, the caip 36 is turnably mounted in the door 37 and is provided with a handle 38. The pins 24a having the combination members attached thereto, are

F rom the foregoing description it will be readily seen that Ihave produced such a device as substantially Vf'ullills the objectsof the invention as set forth herein.

While this specification sets forthV in de- 'l tailv the present and preferred construction of the device, still in practice suchY deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claims.

Having thus described my invention, what I claim as new and useful and desire to 'secure by Letters Patent is: l
